To all whom it may concern Be it known that l", Greener. C. Jensen, ecitizen of the United States, residing Dalrland, in the county ofAlameda and @rtate of California, have invented certain new and usefulimprovements in Locking Apparatus for Levers, of which the following isa specification.

. -The present invention relates to an improved locking apparatusparticularly de signed for employment in connection with the gear shiftlever of a motor driven vehicle, and has for its principal object toprovide a construction which is capable of being incorporated with alever mounted for lateral Swinging movement relative to a supportingvshaft, fulcrumed for pivotal movement at? right angles to the axis ofswinging movement of the lever. Another object, is to provide aconstruction which will lock the lever from What is commonly termed,selective or operative movements;

to provide a lock controlled means adapted,

for automatic engagement with a locking bolt on the movement of saidboltto engage the lever.

With the above mentioned and other ob jects in. view, the inventionconsists in the novel construction and combination of parts hereinafterdescribed.

To more-fully comprehend the invention, reference is directed to theaccompanying drawings, wherein,

Figure l is a vertical sectional view through the preferred embodimentof my invention, with a. lever locking bolt and holt locking pin inlocking position.

Fig. 2 is a transverse sectional View taken on the line 22 of Fig. 1.

Referring more particularly to the several -views of the drawings,wherein like characters of reference designate corresponding parts,

. 1,- indic'ates a lever casing, tubular in form and upwardly throughwhich, extends a suitable lever 2. The lever is provided with atransverse opening or bore 3, the valls'oi 'Which taper as at l, fromthe center or" the versely thereof through the opening 3, in

' opening outwardly toward the sidesof said lever as in Fig. 2.Rotatably mounted at its ends in the casing 1, and extending transthelever, is a supporting shaft 5, for said lever, and the lever is securedthereto by a andrearwardly is on the axis of rotation of said shaft 5.but that. lateral movement of" the lever is permitted by the flaring orsuper ing of the wells of the opening 3, from the center thereof towardeach side said lever, thus'universal movement of the lever provided Alever casing cover '7, is positioned over the open top of the levercasing end the some is provided with an opening 8, through which theupper portion of the lever extends.

The lever is formed in its rear wall with a semi-circular cut-out orseat 9, extending in a plane parallel to said shaft 5, and xvi hin saidcut-out 9, extends a lever locking bolt, fulcrumed at its ends as at 9for rota: tion in the lever casing 1. The lever looking bolt 10, isprovided with a recess or depression 11, in the surface thereof, sopositioned, and of such width and depth, that on the some registeringwith that portion of the lever adjacent the cut-out 9*, in the lever,that the solid portion of said "lever is capable of passing therethroughadmitting of universal pivotal uioven'lent of the same. The solidportion of said lever locking bolt 10, is a opted on the rotation oi thebolt to he received in said depression l), and prevent either lateralinoven'ient of said lever on said pin, (5, or forward pivotal movementof the lever on the shaft 5; the locking oil the lever is illustrated inFig. 1 of the d :nwings. The lever locking bolt 10, is further providedon its surface with a semi-circular depression 10 intersecting saiddepression l1, and arranged at approirienutely right angles thereto andsaid depres sion is adapted for receiving the solid portion of a boltlocking pin 1'2, disposed at right angles to said lever lockin bolt it),and rotal'xebly mounted in a vertically disposed cylindrical recess 13,in the lever cesing 1'. The bolt locking pin is also provided on itssurface with a semicircular depresr sion 14, adapted when in registerwith the lever locking bolt 10 to permit of free rots.- tion oi the sameto locired and unlocked position. The upper portion 01' the bolt lockingpin 12, is provided with a tongue 14, adapted to contact with 'aeorrespoiding tongue 15, depending from the underside of akey-controlled locking barrel i6, roteleobly mounted in a locking barrelcasing 17, positioned. in suitable recess 18, in then'pper portion oithe lever casing l. The rotetion oi the looking hat-rel '16, aone-quarter revs lution in a counter-clockwise direction, causes thetongue 15, to engage its cooperating tonguel i, and to rotate the boltlocking pin 12, to position the cut-out 14 thereof in cooperation withthe lever locking bolt 10, thus rotating the solid portion of the boltlockingpin from its recess in the bolt 10, and permitting the rotationof the lever locking bolt to' admit of the solid portion thereof to beremoved from the depression 9, in the lever, and be received in saiddepression 14, in the bolt locking pin, thus enabling the lever to beswung on its fulcrum. A spring 19, coiled about the lower portion of thebolt locking pin 12 is secured. at one end, as at 20, to the levercasing 1, and at its opposite end is attached as at 21, to the boltlocking pin 12, causing a one-quarter revolution of the bolt locking pinon the movement of the lever locking bolt from locked to unlockedposition relative to the lever, thus, it will be apparent, that on thelocking of the lever from operative movement the bolt locking pinautomatically locks said lever locking bolt in its locking position.

The rotation of the lever locking bolt 10,

is easily accomplished by grasping the handle 22, connected to one endthereof which extends preferably exterior-1y of tliepast l.

Having thus described my invention what [I claim 1. In combination witha lover a .shaft )assing through the same and providing a fulcrumtherefor and relative to which said lever is capable of lateral pivotalmovement, said lever being provided in its surface in -alinement withsaid shaft with a depression extending parallel to said shaft, arotatable lever locking bolt disposed in a plane parallel with saiddepression and passing through the same to lock said lever frommovement, said rotatable bolt being disposed parallel with said shaftand rovided with a depression of a length equa to the width of the leverand adapted on the rotation of said bolt to permit passage therethroughof that portion of the lever adjacent said dearms? pression to admit ofoperative movement or the lever, a rotatable bolt locking pin arrangedat right angles to said bolt and adapted for rotation to intersect theaxis of rotation of said bolt when in its locked position, and arotatable key-controlled locking barrel arranged in alinement with saidlook ing pin and adapted-for rotation to rotate said pin to permltmovement of the bolt to unlocked position.

2. In combination with a tubular lever casing, a lever extendedtherethrough and provided with an opening therein, said openingincreasing in diameter from its center to its opposite ends, a shaftpassin through said opening and supporting the ever and providing afulcrum therefor, a pin extending transversely through said opening atits center and passing through said siaft said lever being provided witha depression in its outer surface adjacent to said shaft, said levercasing provided with a transverse bore intersecting the tubular portionthereof, a lever locking bolt disposed within said bore and capable ofaxial rotation therein for positioning the surface thereof within saiddepression to look the lever from move ment, said bolt being providedwith intersecting depressions one adapted on the axial rotation of thebolt forregistering with the depression in said lever to permit thesurface of the lever to pass through the same, said casing being furtherprovided with a bore open at one end and intersecting said looking boltreceiving bore, a rotatable bolt looking pin within said bore andprovided in its surface with a depression, the said pin 7 adapted forreception within the other depression in said bolt to lock the same frommovement, and a lock controlled mechanism for rotating the pin in areverse direction.

In testimony whereof I have signed my name to this specification in thepresence of a subscribing witness.
